The 6th Patriarch of Zen, Hui-neng (early 8th c. China) made some very profound comments on the Lotus Sutra in the "Platform Sutra" - the only Chinese-origin sutra in the entire Mahayana canon. The Platform Sutra is a medium length work in 57 Chapters. It is regarded as the principal, and indeed the only, sutra of the Zen path, which path generally eschews any reliance upon the printed or written word.
